With run consumption down to 87µA/MHz, 440nA stop mode with full RAM data retention, a low-power time counter, and fast wakeup time of 3.5µs the STM32L0 allows applications to maximize use of energy-saving modes. The STM32L0 series enables designers of products such as computer peripherals, healthcare monitors and trackers, industrial sensors, and smart-home devices to deliver market-leading battery life and create slim and lightweight new styles. Where other devices suffer rapidly increasing current consumption at higher temperatures, ST’s unique process technology maintains stability over a wide temperature range, ensuring these devices offer the world’s lowest power consumption at 125°C. The STM32L0 series also has the world’s lowest Analog-to-Digital Converter (ADC) power consumption. The 12-bit on-chip ADC draws only 48µA when operating at 100ksample/s. Built-in hardware oversampling increases the ADC resolution to 16-bits.

Over 30 part numbers offer basic entry-level configurations as well as variants featuring USB connectivity with the option of an LCD controller up to 8×28. USB full-speed enabled devices support crystal-less operation, USB Battery Charger Detection (BCD), and energy-saving Link Power Management (LPM).
